This
slide set was chosen to show some of the best examples of volcanic landforms
on Mars, visible in images returned by the two Viking Orbiter spacecraft.
The set of 20 slides cannot provide an exhaustive treatment of volcanism
on Mars, but it should serve as an overview to the subject. For a more
detailed description of the various interpretations proposed for individual
volcanoes on Mars, please refer to the list of references provided at
the end.
